Description

A negative valve is a type of valve that is used in milking machines to regulate the vacuum pressure applied to the cows during milking. It is designed to help prevent over-milking, reduce stress on the cow, and improve the overall efficiency of the milking process.

In a milking machine, the vacuum pressure is created by a vacuum pump, which draws air out of the system and creates a negative pressure. When the vacuum pressure is applied to the udder, it causes milk to be extracted from the cow’s teats.

However, if the vacuum pressure is too high or applied for too long, it can cause damage to the cow’s udder and lead to reduced milk production, discomfort, and even issues such as mastitis. This is where the negative valve comes in.

The negative valve is a device that automatically regulates the vacuum pressure applied to the cow’s udder. It senses when the vacuum pressure becomes too high and opens a release valve to allow air into the system, reducing the negative pressure.

This helps to prevent over-milking and reduces the risk of injury or stress to the cow. It also helps to ensure efficient milk extraction by applying the vacuum pressure only when milk is being extracted, rather than continuously.
